29 * DOC: Introduction
30 *
31 * cfg80211 is the configuration API for 802.11 devices in Linux. It bridges
32 * userspace and drivers, and offers some utility functionality associated
33 * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used
34 * by all modern wireless drivers in Linux, so that they offer a consistent
35 * API through nl80211. For backward compatibility, cfg80211 also offers
36 * wireless extensions to userspace, but hides them from drivers completely.
37 *
38 * Additionally, cfg80211 contains code to help enforce regulatory spectrum
39 * use restrictions.

43/**
44 * DOC: Device registration
45 *
46 * In order for a driver to use cfg80211, it must register the hardware device
47 * with cfg80211. This happens through a number of hardware capability structs
48 * described below.
49 *
50 * The fundamental structure for each device is the 'wiphy', of which each
51 * instance describes a physical wireless device connected to the system. Each
52 * such wiphy can have zero, one, or many virtual interfaces associated with
53 * it, which need to be identified as such by pointing the network interface's
54 * @ieee80211_ptr pointer to a &struct wireless_dev which further describes
55 * the wireless part of the interface, normally this struct is embedded in the
56 * network interface's private data area. Drivers can optionally allow creating
57 * or destroying virtual interfaces on the fly, but without at least one or the
58 * ability to create some the wireless device isn't useful.
59 *
60 * Each wiphy structure contains device capability information, and also has
61 * a pointer to the various operations the driver offers. The definitions and
62 * structures here describe these capabilities in detail.

692 * The scanning process itself is fairly simple, but cfg80211 offers quite
693 * a bit of helper functionality. To start a scan, the scan operation will
694 * be invoked with a scan definition. This scan definition contains the
695 * channels to scan, and the SSIDs to send probe requests for (including the
696 * wildcard, if desired). A passive scan is indicated by having no SSIDs to
697 * probe. Additionally, a scan request may contain extra information elements
698 * that should be added to the probe request. The IEs are guaranteed to be
699 * well-formed, and will not exceed the maximum length the driver advertised
700 * in the wiphy structure.
701 *
702 * When scanning finds a BSS, cfg80211 needs to be notified of that, because
703 * it is responsible for maintaining the BSS list; the driver should not
704 * maintain a list itself. For this notification, various functions exist.
705 *
706 * Since drivers do not maintain a BSS list, there are also a number of
707 * functions to search for a BSS and obtain information about it from the
708 * BSS structure cfg80211 maintains. The BSS list is also made available
709 * to userspace.

1140 *
Johannes Berg04a773a2009-04-19 21:24:32 +02001141 * @join_ibss: Join the specified IBSS (or create if necessary). Once done, call

Johannes Bergd3236552009-04-20 14:31:42 +02001375 * has its own custom regulatory domain and cannot identify the
1376 * ISO / IEC 3166 alpha2 it belongs to. When this is enabled
1377 * we will disregard the first regulatory hint (when the
1378 * initiator is %REGDOM_SET_BY_CORE).
Johannes Berg5be83de2009-11-19 00:56:28 +01001379 * @WIPHY_FLAG_STRICT_REGULATORY: tells us the driver for this device will
1380 * ignore regulatory domain settings until it gets its own regulatory
Luis R. Rodriguez749b5272010-10-20 10:18:54 -07001381 * domain via its regulatory_hint() unless the regulatory hint is
1382 * from a country IE. After its gets its own regulatory domain it will
1383 * only allow further regulatory domain settings to further enhance
1384 * compliance. For example if channel 13 and 14 are disabled by this
1385 * regulatory domain no user regulatory domain can enable these channels
1386 * at a later time. This can be used for devices which do not have
1387 * calibration information guaranteed for frequencies or settings
1388 * outside of its regulatory domain.
Johannes Berg5be83de2009-11-19 00:56:28 +01001389 * @WIPHY_FLAG_DISABLE_BEACON_HINTS: enable this if your driver needs to ensure
1390 * that passive scan flags and beaconing flags may not be lifted by
1391 * cfg80211 due to regulatory beacon hints. For more information on beacon
Luis R. Rodriguez37184242009-07-30 17:43:48 -07001392 * hints read the documenation for regulatory_hint_found_beacon()
Johannes Berg5be83de2009-11-19 00:56:28 +01001393 * @WIPHY_FLAG_NETNS_OK: if not set, do not allow changing the netns of this
1394 * wiphy at all
1395 * @WIPHY_FLAG_PS_ON_BY_DEFAULT: if set to true, powersave will be enabled
1396 * by default -- this flag will be set depending on the kernel's default
1397 * on wiphy_new(), but can be changed by the driver if it has a good
1398 * reason to override the default
Johannes Berg9bc383d2009-11-19 11:55:19 +01001399 * @WIPHY_FLAG_4ADDR_AP: supports 4addr mode even on AP (with a single station
1400 * on a VLAN interface)
1401 * @WIPHY_FLAG_4ADDR_STATION: supports 4addr mode even as a station
Johannes Bergc0692b82010-08-27 14:26:53 +03001402 * @WIPHY_FLAG_CONTROL_PORT_PROTOCOL: This device supports setting the
1403 * control port protocol ethertype. The device also honours the
1404 * control_port_no_encrypt flag.
Johannes Berge31b8212010-10-05 19:39:30 +02001405 * @WIPHY_FLAG_IBSS_RSN: The device supports IBSS RSN.

1434 * the reg_notifier's request can be passed as NULL
Johannes Bergd3236552009-04-20 14:31:42 +02001435 * @regd: the driver's regulatory domain, if one was requested via
1436 * the regulatory_hint() API. This can be used by the driver
1437 * on the reg_notifier() if it chooses to ignore future
1438 * regulatory domain changes caused by other drivers.
1439 * @signal_type: signal type reported in &struct cfg80211_bss.
1440 * @cipher_suites: supported cipher suites
1441 * @n_cipher_suites: number of supported cipher suites
Jouni Malinenb9a5f8ca2009-04-20 18:39:05 +02001442 * @retry_short: Retry limit for short frames (dot11ShortRetryLimit)

Johannes Bergef15aac2010-01-20 12:02:33 +01001448 * @perm_addr: permanent MAC address of this device
1449 * @addr_mask: If the device supports multiple MAC addresses by masking,
1450 * set this to a mask with variable bits set to 1, e.g. if the last
1451 * four bits are variable then set it to 00:...:00:0f. The actual
1452 * variable bits shall be determined by the interfaces added, with
1453 * interfaces not matching the mask being rejected to be brought up.
1454 * @n_addresses: number of addresses in @addresses.
1455 * @addresses: If the device has more than one address, set this pointer
1456 * to a list of addresses (6 bytes each). The first one will be used
1457 * by default for perm_addr. In this case, the mask should be set to
1458 * all-zeroes. In this case it is assumed that the device can handle

1471 * any given scan
1472 * @max_scan_ie_len: maximum length of user-controlled IEs device can
1473 * add to probe request frames transmitted during a scan, must not
1474 * include fixed IEs like supported rates
1475 * @coverage_class: current coverage class
1476 * @fw_version: firmware version for ethtool reporting
1477 * @hw_version: hardware version for ethtool reporting
1478 * @max_num_pmkids: maximum number of PMKIDs supported by device
